This Design Idea is a two-wire current regulator that strikes a good balance between performance and parts count. Employing three transistors, three resistors, and one LED, it achieves good regulation ...

TFETs are on track to solve power leakage and heat problems of regular transistors and delivering comparable performance to today’s transistors, but with much greater energy efficiency. They do this ...

You know the “just add a transistor” drill by now: a performance or functionality requirement comes up that you can’t support entirely using the blocks built into your favorite mixed-signal ...

Researchers have developed a single-atom transistor, the world's smallest. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the ...

Researchers have designed a novel computing system made solely from carbon that might one day replace the silicon transistors that power today’s electronic devices. It is a spintronic device that ...

Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. However, ...

Intelligent soft switching with AI support promises to reduce switching losses in power transistors by up to 95 per cent. Porsche Engineering is already ...

Brushless motor construction includes stator windings and permanent-magnet rotors, similar to that of ac permanent-magnet synchronous motors. Too, in brushless dc motors the commutation (that process ...

Organic light-emitting diode (OLED) displays are currently found on mobile phones and digital cameras. But in the future, manufacturers expect bigger, bendable, and completely transparent versions.
